RegisterCustomSchemeHandler won't let do fetch and XMLHttpRequest requests.

[jakerdy]

Hi,

I am evaluating Photino as a replacement for Electron. While testing how I could wrap our RPC implementation using Photino APIs, I encountered a problem with CustomSchemeHandlers.

For "heavy" messages, we used HTTP requests. However, with Photino, I thought custom URLs like "rpc://my-method" could be used to avoid passing data through the network. But when my JavaScript code tries to fetch data using these custom URLs, it simply doesn't work.

This issue is easily reproducible. Just create a template project, open the developer tools, and run this line:

await fetch("app://asdf.txt");

The same issue occurs with XMLHttpRequest.

Should this even work for fetch, or is it just a feature for ?

I am running on Windows 11 with .NET 9.0 and the latest Photino version (3.2.3).
